Ending Fraying & Fuzzy Edges: Carbide Blades for High-Performance Fibers

Writer： admin Time：2026-03-04 11:16:49

In the manufacturing of high-end cut-resistant gloves, fibers like Aramid provide exceptional protection but create a common cutting challenge: fraying and fuzzy edges.

This defect occurs when a blade fails to sever the tough fibers cleanly, leaving them pulled and damaged. This compromises not only the appearance but also the structural integrity and reliability of the final product. Overcoming this requires a cutting solution that combines extreme sharpness, superior wear resistance, and an optimized shear angle.

The Customer Feedback

"We tested many blades, but with these high-tenacity fibers, ordinary solutions always left fraying at the cut edge," explained the Technical Director for a manufacturer of protective wear. "That changed when we started using HAO Carbide's custom 100*22*0.2mm carbide blades, specifically the 19° edge design.

The carbide substrate provides lasting sharpness, but the precise 19° angle is what makes the difference—it seems perfectly matched to our material. It changed the dynamics of the cut, achieving a clean shear that eliminates fiber tearing at the source. Now, cutting is no longer a bottleneck; our line runs smoothly and delivers a consistently perfect finish."
